Remarks

• Systematics: Kiritshenko described Ph. incertus from female larva III, supposing that it was adult female. Ome type slide with one female was examined in Danzig (2006a) and it was designated as a lectotype. Probably, this specimen was described by Borchsenius (1949) and Tereznikova (1975). The drawing by Tereznikova differs from the specimen mentioned above in the absence of ventral tubular ducts in the medial part of thorax and large ones in the medial part of the ventral surface of the body (perhaps these ducts were overlooked). (Danzig, 2006a) Danzig & Gavrilov-Zimin, 2014 noted that the original description and figure of Paroudablis brachipocii Sazvescu, does not differ from Fonscolombia incerta.
• Structure: Female. Body oval, from pink to lemon yellow; 2.5 mm. Antennae 9-segmented. Legs comparatively short, with thick hind femur. Anal ring with incomplete outer row of pores and short slender setae. Circulus absent. Multilocular pores situated on 3-4 posterior sternites of abdomen. Quinquelocular pores absent. Dorsal tubular ducts forming transverse rows on all tergites. Ventral ducts forming rows and bands on abdomen, arranged along body margin; groups of ventral ducts and singular ones also occur on thorax. Dorsal and marginal ventral ducts twice as large as majority of ventral medial ones, but some medial ventral ducts of the same size as dorsal ducts. (Danzig, 2006a)
• Biology: Occurring on the roots of grasses.
• General Remarks: Acceptance of the synonymy of Paroudablis with Phenacoccus (see Danzig, 1980b) necessitates the new combination of this species. Good description and illustration of the adult female given by Savescu (1985).Good description and illustration of the adult female given by Tereznikova (1975). Good description of the adult female given by Borchsenius (1949), Kosztarab & Kozár (1988F) and by Tang (1992).Good description and illustration of the adult female given by Tereznikova (1979). Good description of the adult female given by Tang (1992).
